POULTRY-RAISNG APPARATUS. p

Application filed January 2, 1923. Serial N'o. 610,353.

To (1 /ZZ 1072.072?, t may concern.:

Be it known that I, Borna O. SrnA'rLrNe, a citizen oit the United States, residing at Opelika, in the county ot Lee and State ot' Alabama, have invented a new and useful Poultry-Blaising Apparatus, ci' which the -following is a speciiication.

This invention relates to apparatus for use in raising poultry and more especially to ine-ans whereby incubators and broeders can be heated etliciently by radiation, itl being- Another object is to provide a structure utilizing a cover sheet or unit for transmitting heat to the eggs or chicks in the structure, whereby approximately the same 'resuits are obtained as wherethey are heated by the body of a hen.

A further object is to provide a structure of this character with novel means for ventilating the same without allowing cool fresh air to come into direct contact with the contents being treated.

A still further object` is to provide a structure of this character utilizing a humidity supplying means o'lI' novel form.

lVith the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certa-in novel details of construction and combina-V tions of parts which will be hereinafter more fully described and pointed out inthel` claims, it being" understood that various changes may be made in the construction and arrangement ot the parts without departing from the spirit of the invention as claimed.`

In the. acconnjiunying drawings the preferred form of the invention has been shown.

In said drawings- Figure 1 isa section through an incubator having the present improvements combined therewith. y y i Figure Q is a section through a brooder having the present improvements.

Referring to the figures; by characters of reference, 1 designates the bottom section oit the housing or' the structure and to this structure is hingedly `or otherwise connected the. top section 2. The twosections normally rest one on top of the other so as to copass directly to saidoperateto form. a complete housing and suitable supports 3 serve to hold the bottom ot' the section 1 oil of the structure on which the device rests. Openings 11 are provided in the bottom of section 1 so that fresh air is free to enter the structure below a pan 5 supported on cleats 6 within the section 1. The walls of the pan are spaced from the walls of section 1 andthe pan is provided with a layer of clean, white sand 7.

A handle 8 is shown at one end of the pan. l

Two oi' these handles may be provided to facilitate raising and lowering the pan in the section 1. A thermometer is also located in the pan, as shown at 9.

Secured in the' lower portion of the upper l section 2 is a plate 10 having a large opening 11 in which is secured a dome-like reflector 12. Suitable insulating material 13 is packed within section 2 above plate 10 and reiector `12.

A cover plate 1e is supported below plate i 10 and is spaced therefrom, this cover plate extending pastvthe margin of the reilector .12, thus to conceal the reflector. Openings 15- are provided 1n the cover plate and vsupported over these openings is a shield plate 16 parallel with plate 14. A bracket 17 is mountedon the vcover plate andA supports .the socket 18 of an` incandescent lamp 19.

An insulation block 2O `is secured `to and supported under the cover plate 111 and is...

tact One `end ot a thermostatstrip 23 preferably formed ot'laminated metals having diil'erent coetlicients of expansion', `1s

`secured toi the binding post 21, and the other end ofthe strip normally engages with the contact 22.

the lamp socket by conductors 24 and when lWhen the lamp 19 is `energized the heat and light rays will flow to the cove-r plate 14 and those rays which are dissipated from the lamp away L lected back to the plate. Thus the heat will be spread throughout the width and` length ot the structure and fresh air enter4 ing the openings t will rise within the" section 1 and be thoroughly heated. The

Both the contact and the binding'. post are electrically connected' with l'rom the plate will be re.y

Aprovided with ya binding post 21 and a con- :the .strip 23 is in normal posi-tion. a circuit` llO Cil

. heated walls of the pan t will prevent the cool fresh air from coming into contact with the eggs because the walls are extended above the eggs. When the temperature begins to rise above the desired degree, the thermostat strip .23 will curl out of engagement with contact 23 and the circuit to the lamp will thus be broken and the generation ot heat stopped. It will be understood that the :tresh cool air rising within the structure will circulate along, around and through the plate 11i so as to be properly before coming intocontact with the efrV` '.i`l1e opening or lifting or' the top ot tac structure at intervals during the first fourteen days of incubation will allow the used air to escape from the structure and be displaced by fresh air entering the open ings l. lifter the fourteen day period mentioned the top 2 can be slightly lifted to provide an outlet for air or, if desired, open ings can be provided in the walls o the structure at points above the top of the pan for the outliow of the air. Such openings have been indicated at Llfin Fig. 1.

by placing moisture in the sand 7.

in the construction of a brooder, as shown in Figure 2, the upper section 25 is fitted snugly to the lower secti-on 26, and this upper section has a` dome-like reflector 27 above which is a suitable insulating material 28. A dished cover plate 29 is supported from the reflector and is adapted'to hang withinthe lower section 2G. This Acover plate has openings 30 over which is supported a shield plate 3l'. A.. bracket 32 supports a. lamp socket below the reflector plate 2T and a lamp 34 is carried by the socket. yObviously the heat of the lamp will be. direc-ted botlrdirectly andby reflection toward the cove-r plate which, in turn, will distribute. the heat throughout the width and length of the brooder. The shield plate 3l, as well'as the plate 16 in Figure l, will prevent the light andfheat rays from passing directly from the lainp to the or to the chicks in the structure. Any suitable arrangement of 'cloths mayv be provided in addition to the structures shown for the purpose of better hovering the chicks.

Sufficient hun'iidit57 can be supplied to the lVhat is claimed isz- 1. In a structure of the class described, the combination with upper and lo-wer sections movably connected, of a reflector carried by the upper section, insulation interposed betwcen the` reflector and the upper section, a cover plate under and spaced from the reflector, a heater interposed between the reflector and the cover plate, an egg holding pan below the cover plate, and means for directing fresh air through the bottom of the structure and around the pan to the heater.

Y In a structure of the class described, the combination with movabl7 connected upper and lower sections, and a heating means within the upper section, of a pan supported in the lower section and spaced;`

from the bottoni and walls thereof, a layer of granular egg-supporting means in the pan, and means for directing fresh air through the bottom of the structure and under the pan, said pan constituting means.

for spreading the air to the walls of the. structure and delivering it into the structure above the level of the supported eggs.

3. In a structure of the class described the combination with upper and lower sec-:gA

tions movably connected, of a dome-likey heat and light reflector supported within the upper sectionk and spaced from the top thereof, insulating material interposed between the top of' the` upper section and the;

reflector, a cover plate connected to the ymarginal porti-on or' the reflector and havdirect passage or' light rays from the lamp;`

to the. opening.

In testimony that I cla-iin 'the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
